Abstract: 607,615. Wiring packages &c. BURGESS, A. F., (Signode Steel Strapping Co.). Nov. 26, 1945, No. 31841. [Class 45] A support for carrying a tool used in the application of tensioned reinforcing or binding strap or wire about packages consists, as shown in Fig. 1, of a pedestal A having a bracket to which is attached a laterally-projecting arm D having a tool-carrier E at its free end and spring-biassed to move the tool-carrier upwardly, such arm including a lever and a parallel link pivotally attached to the tool-carrier and bracket. The pedestal A comprises two telescopic tubes 5, 6, the upper 6 of which carries a bracket in the form of two parallel plates 56, Fig. 9, to which the arm D is pivoted; the plates 56 are welded in slots in the upper end of the tube 6. The arm D comprises a pair of parallel levers 58 which are pivoted at 59 to the plates 56 and have pivoted between their outer ends at 66 the flat stem 65 of the tool carrier E. The upper end of the stem 65 is provided with an elongated slot 95 for engagement by a pin 96 on the outer ends of a pair of plates 86 which are secured 6, and extend from, a link 75 pivoted at 76 to the bracket plates 56; this link 75 is disposed between the two levers 58. A compression spring 97 in the slot 95 urges the pin 96 towards the front end of the slot. A tool-attachment plate 70 is detachably pivoted by means of a spring- pressed knurled-headed stud 71, Fig. 8, to a lateral and bifurcated flange 69 on the stem 65. The arm D is counterweighted by means of a spring 105 which, as shown in Fig. 4, is housed in the pedestal A. The upper end of the spring is connected to a rod 110, Fig. 9, which is hooked around the barrel of a pin 112 resting in notches in the levers 58, and the lower end of the spring is connected to a tensioning rod 107, Fig. 4, which is threaded for adjustment by a nut 109 engaging a cap 108 at the lower end of the upper tube 6. The tension of the spring 105 may be adjusted so as either actually to lift the tool from the package or merely to counterbalance the tool. The lower pedestal tube 5, Fig. 4, is pivoted on a bolt 11 passing through the upstanding flanges 9, 10 of a bracket B. Abutment screws 17 passing through webs 15 on the bracket B serve as adjustable stops to permit a certain limited swing of the pedestal. When the bracket is secured to the floor as shown in Fig. 4, the screws 17 engage the sides of the tube 5, and, when the bracket is secured to a wall as shown in Fig. 15, they engage the opposite sides of a lug 25 on the tube 5. The inner and upper tube 6 is provided with a collar 38 which is screwed on the tube by a clamping screw 42, the collar being prevented from rotating on the tube by means of a washer 43 which is disposed between the jaws of the collar and engages a slot 44 in the tube. Normally, the collar 38 rests upon a collar'35 which is fixed at the top of the tube 5 so that, by adjusting the position of the collar 38 on the tube 6, it is possible to vary the height of the pedestal. The upper tube 6, together with the arm D, may be swung through 90 degrees to a position on either side of its central packaging position, a flat surface face on the collar 38 engaging an upstanding flange 37, Fig. 1, on the collar 35 in either of these positions. The rear parts of the upper and lower contacting surfaces of the collars 35, 38 are bevelled so as to cause the upper tube 6 and arm D to tend to lie with the arm over the package. After a package has been placed in position on the bench as shown in Fig. 1, the operator pulls the tool forward so that the pedestal hinges about its base bracket B and then swings it horizontally from a position at one side of binding position to a position directly over the package. The tool is then lowered on to the package for tying, after which the tool and carrier can be moved to allow for the removal of the package. Specification 585,004, [Group XV], is referred to.
